Changing A Bar From Fast/slow To Semi/full

[deerslayer]

Well, with the BAR shooting taking ahold of me about as bad as thompsonitis, I was wondering if it was easy to take a A2 type bar with fast and slow full auto settings and make it a semi/full auto type gun. I have an extra complete trigger group. I seem to remember seeing or being told how to do this, but don't remember what to do, or where I saw it.

 

So, if anybody has a way to do this I'd appreciate the help. I was actually thinking of modifying the trigger group to have the pistol grip seen on a Monitor (and maybe dress it up on monitor type wood). I had a monitor trigger group for a little while while I was making the grip panels for someone and liked the feel of the gun in that configuration.

Dan,

I don't own a BAR, but I recently read something on Subguns or maybe Srurm.

As I remember, You remove the stock, take out the spring and piston, reverse order -- putting spring against the receiver and the piston at the rear of tube and reassemble.

I imagine you could also just leave the spring and piston out, but then they may become lost.

Let me know if I got it right.

Seems right, that was me asking the same question on subguns. I'll give it a try this weekend!!

The M1918 - WW 1 BARs were semi & full. Seems like I remember reading that the maroons kept this feature till WW 2. Oh well they had kept the 03 Springfield too, untill after Okinawa.

No idea how hard it would be to find one of those trigger groups or the parts for it - trigger group frame is the same.

www.1918a2.com. They have semi/full trigger groups and other parts as well. These trigger groups are $350 plus shipping. Hope that helps.

You can do things to affect a return to semi-auto operation with the selector set in the "slow" setting in a M1918A2 trigger group:

 

One, simply remove the actuator and its spring. Easily done by removing the stock and the actuator tube for gaining access.

 

-or-

 

Two, you can remove the sear stop lever from the trigger group.

 

Either action has the same effect in that it prevents release of the sear automatically by the action of the rebounding actuator against the sear release. With either part removed you will need to manually release the trigger fully to reset its disconnect function for the next and subsequent shots. If the selector is set again at the "fast" setting the automatic function will be unaffected but at the "fast" rate.

I found this old tech info on Youtube. It looks like all that is needed it to put the cam release buffer to the back of the spring. Here is the Youtube site.
